A new report indicates that Special Counsel Robert Mueller warned President Trump’s lawyers about a possible subpoena for the commander in chief if he refused to talk to Mueller’s team.

The Washington Post reports that Trump’s lawyers “insisted he had no obligation to talk with federal investigators probing Russia’s interference in the 2016 presidential campaign.”

In response, Mueller reportedly brought up the possibility of issuing “a subpoena for the president to appear before a grand jury.”
